IMPROVEMENT IN FLUTINGMACHINES.

Specication forming part of Letters Patent No. 55,469, dated June 12,1866.

To all whom it may concern:

Be it known that-I, Mrs. HENRIETTA H. COLE, of the city, county, andState of New York, have invented new and useful Improvements inFluting-Machines; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specilication.

Ihe present invention relates to machines for making iiuting-trim ming,77 so called, used by ladies in the trimming of their dresses, Sac.;and it consists in so arranging one of the two luted rollers, betweenwhich the material, such as linen, lace, Sac., is passed, that thepressure of such roller thereon can be immediately released and theroller raised in order to allow the material passing between them to beremoved at any point of its length; and, furthermore, it consists in anarrangement of parts whereby the pressure ot' the upper roller upon thematerial passing between it, and the lower roller, which turns in astationary bearing, can be adjusted at pleasure, so as to produce agreater or lesser amount of pressure upon the material, according as maybe desired.

Heretofore, when desired to remove thematerial being fluted from therollers before the whole length of the material has passed through, ithas been necessary to reverse the motion of the rollers, thus causingthe material to travel or feed back, the great `objection to which wasthat as the material repassed between the rollers it necessarilyproduced irregularity in the fluting, which, as is obvious, wasexceedingly disadvantageous; but by my improvements this objection isentirely obviated, as will be readily apparent from the following detaildescription of the machine, reference being had to the accompanyingplateof drawings, in which-h Figure l is a View of one side of the ma-ychine; and Fig. 2, a transverse vertical section taken in the plane ofthe line x m, Fig. 1.

Similar letters of reference indicate like parts.

A in the drawings represents the bed-plate of the machine, which may beeither the top of a table, or a separate piece of wood or other suitablematerial, or the table of a sewing-machine; B B, two rollers placed oneabove the other, the peripheries of each of which are to be similarlytluted in the direction of their length. These rollers, by theirextension-shafts or spin.- dles C, at one end turn in bearings of boxesD D, placed one above the other, but in two places, at one end, E, ofthebed-plate A. These boxes are placed over xed upright guideposts, F, ofthe bed A, to which, by nuts G, the lower one in each case is fastenedand held firmly in place upon the bed-plate A, whereas the upper boxesrest upon spiral springs H otl the said posts F, and are so arranged asto play loosely up and down thereon; I, a crank or. winch-handle,secured to the outer end of the lower roller-spindle or shaft,

O, for convenience in turning the rollers by, the upper roller turningin connection with the lower, through the medium of the iiuted surfacesor peripheries, or by means of gearwheel J, secured to theroller-spindles O.

To the upper end of one of each of the two guide-11)osts,F,for the upperroller-boxes a leverarm, K, is hung, extending over an d across theupper end of the boxes, upon a center-piece, L, of which it rests, uponwhich lever is arranged a weight, M, having set-screw N, in such amanner that it can be adjusted to any position thereon, and thus holdthe upper roller of the machine down upon the lower roller with more or*less pressure, according as may be desired, by releasing which pressureentirely the upper roller is lifted from the roller through the actionof the spiral springs H, upon which the upper boxes rest, as is obviouswithout any further explanation.

With the machine above explained the material to be iiuted is passed inand between the two luted rollers, as in ordinary iiuting-machilies, thepressure,` however, first having been properly adjusted, when, motionbeing communicated to the rollers through the crankhandle I,hereinbefore referred to, or by connecting the pulley R through a beltwith a treadle or other suitable power, the material is drawn throughand between the rollers to the length desired, when to withdraw it, iffor only a portion of its length, the lever-arms K are raised, leavingthe springs Gr free to throw or raise up the upper roller, and thusleave the material susceptible of being readily removed Without runningit back through the machine, the advantages oi' which are obvious toall.

The rollers I intend to arrange in such a manner in their respectivebearings that they can be easily detached therefrom when desired to userollers having larger or smaller corrugations 5 an d as there are manyWell-kn own ways in which this may be accomplished, I do notr deem itnecessary to describe any one particular arrangement therefor, as Iintend to lay no claim to it and it forms no part oi the presentinvention.

I claim as new and desire to secure by Letters Patent- Mns. HENRIETTAII. COLE.
